WATER-COOLING ATTACHMENT FOR REFRIGERATORS.

Application-filed February 5, 1925. Serial No. 7,047.

My invention relates to improvements in a water cooling attachment for refrigerators.

The object of my invention is to provide an attachment which can be readily applied to a refrigerator whereby the water is cooled by having the coil thereof in contact with the ice and having the discharge faucet so arranged that the top'of the refrigerator serves as a support for a glass or thelike.

Another object of my invention is to provide an attachment of this character which can be readily applied to the ordinary refrigerator by boring a single hole through the rear wall of the refgrigerator, communieating with the ice compartment.

A further object of 'my invention is to provide a simple, cheap and eective attachment of this character having certain details of structure and combination -of parts hereinafter more fully t forth.

In the accompanying drawings:

Figure 1 represents the front View of the upper end of the refrigerator showing my improved cooling attachment in the ice compartment of the refrigerator.

Figure 2 is a vertical sectional view taken through the connection inthe rear wall of the refrigerator. I

Figure 8 is a rear yelevation of a refrigerator showing a modified form of my attachment.

Referring now to the drawin s, 1 repre sents an ordinary refrigerator aving the usual ice compartment 2 closed by the door 3 all of which is of the ordinary structure and needs no further description. My improved attachment consists of a coil 4 made in any desired manner, but preferably that shown in Figure 1 of the drawings. The coil 2 is made perfectly fiat and is adapted to standjn a vertical position against the rear wall of the ice compartment 2. The lower end of the coil has connected thereto a vertical pipe 5 which has its upper end connected at (i to the connection 7, and which'forms the inlet for the water from the service pipe. The opposite end of the coil is turned downwardly as indicated at 8, 'and connected at 9 to the connection 7, which I will now proceed to describe.

-The connection 7, as shown in Figure 2 in the drawings is of a Y shape and having a body portion of circular form, and is adapted to pass into a circular opening 11 ing and screw threaded as indicated at 13,'

and upon which is threaded a collar 15 whereby the casting is tightlyl locked in the rear wall of the refrigerator.. The outer end of the 'connection or body portion 10 is provided with two screw threaded open ings 16 and 17 into which arev screwed the elbow connections 18 and 19, as clearly shown in lFigure 2 of the drawings. Connected to the elbow connection 18 is a pipe' 20 which extends upwardly `and over the upper end 21 of the refrigerator and carries the spigot 22. Connected to the connection 19 is a pipe 23 which leads down and is connected to the water service pipe.

From the, foregoing description it-will be seen that the Water enters through the pipe 23 into the passage 24, and through ysaid passage to the pipe 5, and down to the lower end of the coil, and up through the coil into the passage 25, and out ,through the connection and the pipe 20 to the spigot 22.

By this arrangement it will be seen that a large cooling surface is 'obtained with a Acomparatively small coil and the whole thing lies flat against the rear wall of the ice compartment, as shown in Figure 2 of the drawings. This takesup `very little space and the ice will bear against the coil and thoroughly cool the water therein.

In the modification shown in Figure 3 of the drawings, I bore an opening 27, in the rear wall. of the refrigerator and through which the service pipe 284 passes and is connected to the coil 29. The second opening 30 is bored through the rear wall of the refrigerator and through which extends the pipe 31 which corresponds with the pipe 20 of Figure 2 and to which is connected the spigot. By this arrangement the same result is obtained and in some instances it may be preferable to use this modified form.

While I have shown and described these specific means of attaching my improved cooling coil within the ice compartment of the refrigerator, it will be understood that the same can be varied without departing from my invention, asthe invention resides in providing an attachment which can be applied to the ordinary refrigerator.

` Having thus 'fully described my invention what claim is:

1. A Water cooling attachment for refrigerators comprising a coil connected to a single casting extending through the Wall of the ice compartment, and having 'a Water inlet and outlet passage therethrough.

` 2. fr Water cooling attachment for refrigerators comprising a casting secured in the Wall oi the refrigerator and having an inlet and discharge passage therethrough, a coil supported hy the casting against the Wall of the ice compartment and having its ende communicating With the inlet and discharge passage, a service pipe connected to a casting on the outside of the refrigerator, and 'a spigot connected to the casting and in com munication With the discharge passage and extending above the upper end of the rerigerator.

In testimony whereof, I have signed this specification.
